[A case of duodenal carcinoid tumor accompanied by liver metastasis and lymph node metastases in a patient with von Recklinghausen disease].

We report a case of duodenal carcinoid tumor accompanied by liver metastasis and lymph node metastases in a patient with von Recklinghausen disease. A 48-year-old woman with von Recklinghausen disease was referred to our hospital because of a submucosal tumor at the ampulla of Vater detected by upper gastrointestinal endoscopy. The lesion was diagnosed as a carcinoid tumor based on the pathology of the biopsy specimen. At operation, although there were liver metastasis on the surface of S3 the liver and regional lymph node metastases, we selected pancreatoduodenectomy with lymph node dissection and enucleation of the liver metastasis. The postoperative course was good and the woman was discharged on postoperative day 33. No recurrence has been seen at 24 months since surgery.
